Bone drops staff sling, not frump. Good luck getting it, he has a 100 item drop table and since the nerf you can only kill him a few times per char.

Why are you only able to kill him 'a few' times?

I would call it an oversight that could be prevented. If Bonesnarl has such a massive drop table, OF COURSE players will camp him without end until they get the item they seek. If only his table were slimmed up a little, and have those drops spread out amongst some of the other creatures of the isle: marsh lights, all the types of zombies, skeletons, etc, even add a few to the Young Hobgoblins etc... The results will be LESS players camping Bone, and the DEV-imposed limit of killing Bonesnarl no more than 10 times per player, will no longer be needed!
